This is, to me, what is missing from this entire thing. Kanye is bipolar, yes, but I don't think anything he's points to some kind of manic outburst. What he said over the past few weeks have be fairly mainstream (or sub-mainstream) conservative talking points. Maybe not the ones that get blasted on Fox News, but the ones that shared and like with Fox News posts on Facebook.
To me the "Kanye is mentally ill" is a cover to hide some very pervasive talking points in conservative circles. It's an extension of the mass misinformation problems that we as a society have been dealing with since COVID and Kanye is the latest victim.
This is what happens in these discussions: people take the genuinely batshit things he's saying and then generalize them to a point where they're merely stupid, and not batshit. Then they say "well, that might be wrong, but it's not crazy!". Well, you're right: it's not crazy. It's also not what he said.
Also, believing members of your family are impersonators or aliens is something young siblings try to persuade one another all the time. It's not unheard of.
Anyway, my larger point is that we should not tolerate antisemitism because of "crazy". Just because one adds outrageous beliefs on top of hate doesn't excuse the hate.
Kanye West is just pushing conspiracies a little further, into the domestic realm.
What's upsetting is that when ordinary John Does promote conspiracy theories they are shunned, but when it's a successful artist we try to find them excuses.
